Delivering a stand-out bass response, the 10" Powered Subwoofer brings a whole new dimension of deep and detailed clarity to movies and music. With a front-mounted woofer, twin ports and an efficient all-digital 200 Watt amplifier, the NVSUB10 adds a powerful low-frequency impact to mid-sized home theater or audio installations. Its cabinet is constructed of durable MDF for a distortion-free, superior bass experience. The NVSUB10 features signal-sensing power activation to automatically turn on the subwoofer when it receives a signal from the receiver and return it to standby after 15 minutes of no signal. Offering maximum versatility, the Powered Subwoofers were designed to integrate with almost any audio system. Unfiltered LFE / RCA stereo input and output let you easily connect to most modern receivers. And a convenient USB jack can power an optional wireless receiver.
